The most revealing moment in Weird Al Yankovic's parody of Lady Gaga's “Born This Way” (his is called “Perform This Way”) is when he sings the line “every day is Halloween for me.”

Yankovic, who brings his rockin' “The Alpocalypse Tour” to Majestic Theatre on Friday, doesn't deny it. He's been playing dress-up and brilliantly satirizing hits for 30 years.

“That line could apply to me as well, I suppose,” said Yankovic in a telephone interview about his latest tour. “I haven't really counted how many costumes changes but my stock line is I've got three more than Lady Gaga. It's a lot of dress-up every night.”

In this age of segmented audiences and disparate playlists, the three-time Grammy winner is a surprisingly unifying force, despite a penchant for jarring segues song-to-song.

He acknowledged that times are much different from when he broke out on MTV. Audiences may have caught up to him, yet he still manages to live up to his nickname.

“I've always been eclectic, and I've always tried to make my song choices, my genre choices as random as possible,” said Yankovic, 53.

“Our culture is that fractured, and we don't have a unifying communal portal like MTV, something that everybody is watching and enjoying at the same time.

“Everybody is into their own little world. It's more important than ever for me to be touching on a whole lot of various sounds, because the mainstream is very fractured.”

His hits include “Eat It,” “Like a Surgeon,” “Fat,” “Smells Like Nirvana” and “Amish Paradise.” There is no doubt that it's a rite of passage for the famous to be playfully skewered by Weird Al, whose last album was called “Alpocalypse.”

In his world, it makes complete sense (make that nonsense) that a song touting the late comedic actor Charles Nelson Reilly set to the sounds of the White Stripes works next to a Taylor Swift parody or a song lampooning Craigslist.

The latter featured Ray Manzarek of the Doors playing organ. Yankovic simply called the musician (who died May 20) and he agreed to poke some fun at his legacy and some authenticity, too.

“That was amazing. That was totally rock-star fantasy camp for me,” Yankovic said. “It was just amazing for me to work in the studio with Ray and hang out with him for an afternoon.”

Yankovic posted a YouTube video of the “Craigslist” session on the day Manzarek died as a tribute. The Doors' keyboardist played some “Soul Kitchen” organ and touch-bass on a modern Nord Electro 2 keyboard, kicking things off this way: “All right, shall we rock it.”

“You get a sense of his personality,” Yankovic said.

One gets a sense of Yankovic's twisted brain with his bizarre choice to conjure the legend of Reilly (known in the 1970s for “Match Game”) in “CNR.”

“That's one of those random things that I thought was funny,” he explained. “I'm my main focus group. If I think it's funny, I go with it.

“But if that had been focus-group tested, that wouldn't have tested very well. You've got to figure the Venn diagram of people who know of both Charles Nelson Reilly and the White Stripes is probably pretty slim. But it's funny to me.”

“It's not autobiographical,” he said. “But I was a kid with a pretty wild imagination.”
